Summary
Analysis
(May 20) Ann Burden, a teenage girl living alone in a hidden valley after a nuclear war, is afraid. For the past few days, she is seen a thin column of smoke in the distance, and it is getting closer. She remembers how her father, brother, and cousin once went to the nearby town of Ogdentown and found that everyone there had died from radiation. Now, with this new smoke appearing, she worries that someone might be approaching. She does not know if the stranger is dangerous or kind—and that uncertainty scares her.
Ann’s fear of the smoke in the distance shows how much the world has changed since the war. Even the smallest sign of another person feels threatening because survival now depends on staying hidden and careful. Her memory of what happened in Ogdentown—and the loss of her family—makes the fear more personal. The unknown traveler is a reminder of everything Ann has already lost. The fact that she does not know whether to hope or worry says a lot about how lonely and uncertain her life has become.
Themes
(May 21) The smoke is now just on the other side of the ridge near Ann’s valley. She thinks whoever it is has stopped at a crossroads to decide whether to go past or come over the ridge into her valley. If they do, they will see the green trees and know someone is alive there, since everything outside the valley is dead. Ann writes in her journal to help her remember things and feel less alone. She used to wish for someone to come, but now she is not so sure. After hearing a frightened man on the last working radio station talk about how dangerous things had become, she decided it might be safer to hide. That is why she secretly moved her supplies to a cave in the hills.
The traveler’s position near the ridge forces Ann to think about what it really means to be alone. She writes in her journal to feel less isolated, but she is also trying to stay in control. It is clear she wants safety more than company now, especially after hearing how bad things were for others. Hiding her supplies in the cave shows how much she has learned to protect herself, as she makes careful choices to stay safe in a world where almost nothing can be trusted.
Themes
(May 22) The smoke is still there, and Ann thinks the stranger might be exploring the area. He (she thinks it is probably a man) seems to be leaving his supplies at the crossroads while scouting nearby roads. This reminds her of when her family and neighbors tried to search for other survivors. Her parents, brother, and cousin all went south to check on friends—but they never came back. She now believes they all died from the radiation. Since then, she has explored the edges of her valley and seen nothing but dead trees beyond.
